Dennis’ (highpitch’s) custom trigger on his 1968 Besson New Standard 181 is described/pictured in the fourth post down on this linked thread~

is where the middle finger engages with the trigger not shown? The mechanics are difficult to discern from that picture (at least for me).

Dennis, could you provide additional pictures and commentary on the trigger mechanism?

See blue arrow…Dennis designed it to engage with the middle finger of the left hand

Looking at the wider picture...that a LONG ways from where the first finger would be operating the 4th valve (which is what is confusing me).

That makes much more sense seeing it from the complete horn view. That IS a great design!

Seems folks had interest after all! (At least enough to know where to point me.) And now you can count me as another person who finds the design quite intriguing.

Trigger details

Yeah, I'm a euph geek gearhead with some mechanical knowledge.

These detail views were taken during development to show how the linkage works. Pressing inward on the paddle lowers the tuning slide position, and when released it retracts via a hidden spring.

Since the slide is modified to a coaxial tubing type (a slide in a slide in a slide), tuning is effected by rolling the central thumbwheel. No having to detach anything, and can be done on the fly. The thread pitch is such that it stays in place.

I don't have a belly guard, and the only problem is it makes your shirt dirty rubbing on it. I'll get around to fixing that sometime.

I have come to find myself using my social finger on the side valve, and digits 4&5 on the paddle.

Much credit goes to Dan Oberloh in Seattle for taking my ideas and turning them into reality. He may be willing to use this design on other horns.

Here are a couple pictures of another Besson 181 New Standard with a trigger…

Nice job, but pretty much the same as everything else. My left thumb just can't grok that actuator style.

And since there is but one slide, tuning is still fiddly.
